How to work out potential difference circuit
WebV(R1) = I*R1 = 1*6 = 6 volts V(RA) = VR4 = (12 – VR1) = 6 volts Thus: I1 = 6V ÷ RA = 6 ÷ 12 = 0.5A or 500mA I2 = 6V ÷ R4 = 6 ÷ 12 = 0.5A or 500mA Since the resistive values of the two branches are the same at 12Ω, the two branch currents of I1 and I2 are also equal at 0.5A (or 500mA) each.

Web13 jan. 2024 · 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: R R – Equivalent parallel resistance; and R_1 R1 , R_2 R2 WebIn parallel circuits, the electric potential difference across each resistor (ΔV) is the same. The current in a resistor follows Ohm’s law: I = ΔV / R. Since the ΔV is the same for each resistor, the current will be smallest where the resistance is greatest.
