## What is the relationship between diameter and current?

The channel diameter (D), defined as the width of the intensity profile at 10% level, increases with the increasing peak current (Ip) up to 3 kA. The relationship between the two parameters can be represented by the equation, D = 8.36 ln(Ip) + 1.598, where D is in mm and Ip is in kA.

**What is the relationship between diameter and resistance?**

Resistance is inversely proportional to cross sectional area. So if the diameter is halved the cross-sectional area is quartered and the resistance is quadrupled.

### How does diameter affect current?

The greater the diameter of the wire used in household wiring, the greater the maximum current that can safely be carried by the wire.

**How does the diameter and length of the wire affect resistance?**

The greater the diameter the lower the resistance. Provided the cross-section area of the wire is the same the resistance of the wire will increase with length. The longer the wire the higher will be the resistance.

## How does the resistance of a wire change when its diameter is doubled?

From this relation we can conclude that resistance is inversely proportional to area A of the conductor. Area of the conductor becomes 4 times the area of the conductor without doubling the diameter. Thus, we can say that new resistance will decrease four times.

**What would be the relationship of current and voltage using Ohm’s law?**

Ohm’s law defines the relationship between the voltage, current, and resistance in an electric circuit: i = v/r. The current is directly proportional to the voltage and inversely proportional to the resistance.

### Is resistance directly proportional to diameter?

Resistance is inversely proportional to square of diameter .

**What will happen to the resistance in law of diameter?**

Resistance (R) is inversely proportional to Area(A). So if radius is doubled, new area= 4x Area of original wire. As you can see in the picture if you increase the diameter of the wire then the resistance will decrease .

## Why does A thicker wire have less resistance?

The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current.

**How does the resistance affect the current?**

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

### Does voltage increase with length?

Long lengths of wire have more resistance than short lengths. Thus, long lengths of wire will cause a larger voltage drop than shorter lengths.

**What is the relationship between current and resistance?**

The relationship between Voltage, Current and Resistance forms the basis of Ohmâ€™s law. In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down. This means that if the voltage is high the current is high, and if the voltage is low the current is low.

## What is the relationship between resistance and diameter?

In other words, the resistance and diameter have such a close relationship, such as : The same voltage, the longer the diameter, the larger the power; The same current, the shorter the diameter, the larger the power.

**What is the relation between a conductor diameter and current?**

If you increase the voltage, you can reduce the diameter of the conductor, and still support the same power output. Power is voltage times current. The power loss in the wire is proportional to the square of the current and inversely proportional to the square of the diameter.

### What happens when you increase the resistance of a voltage?

Likewise, if we increase the resistance, the current goes down for a given voltage and if we decrease the resistance the current goes up. Which means that if resistance is high current is low and if resistance is low current is high.
