Find the potential difference across resistor
WebJan 13, 2024 · Resistors in parallel formula A parallel circuit is characterized by a common potential difference (voltage) across the ends of all resistors. The equivalent resistance for this kind of circuit is calculated according to the following formula: 1/R = 1/R_1 + 1/R_2 + ... + 1/R_n, 1/R = 1/R1 + 1/R2 + ... + 1/Rn, Where:
Find the potential difference across resistor

WebThe potential across a resistor, also known as voltage drop, describes how much of the supplied energy of a voltage source is reduced when a electric current goes through a passive element, in this case the resistor. WebMar 28, 2024 · The potential difference V V is the amount of work done per unit charge to move a test charge from point A to B without changing its kinetic energy. The total work done when electrons flow through a resistor is: W = Q \cdot V W = Q ⋅ V where: W W — the total work done;
