WebV. I X R. To work out the voltage: current x resistance. To work out the current: voltage / resistance. To work out the resistance: voltage / current. Ohm’s law is shown as: V = IR. The length of a wire: The length of the wire will make a difference. This is because when you have a long wire, the electrons have to squeeze together for longer ... WebJan 23, 2024 · What is the effect of increasing the length of the wire in a single circuit? But increasing the length of the wire increases its resistance and reduces the current for the same potential difference (voltage), per Ohms law V=IR. The work per unit charge in moving the charge along the length of wire does not change unless there is a change in ...
Why does resistance increase with length? - Physics …
WebJul 3, 2024 · Imagine a circuit which consists of a battery and a resistor with a certain wire length. Suppose that the battery supplies 9 Volts. I know that it is the electromotive force which pushes the electrons from the negative terminal to the positive terminal. WebSep 12, 2024 · The resistance can be found using the length of the wire L = 5.00m, the area, and the resistivity of copper ρ = 1.68 × 10 − 8Ω ⋅ m, where R = ρL A. The resistivity and current density can be used to find the electrical field. Solution First, we calculate the … newfound artisan
