WebThe answer is 2.0 Amps. This is a parallel circuit. Each resistor sees exactly the same voltage (assuming negligible wire losses). The current through each resistor is 12V/ (R Ohms) = X Amps, where X = 12/R. The currents through the three resistors (starting from the left) are 1.2A, 0.8A and 2.0A. TOTAL current is 0.8+1.2+2 = 4.0 Amps. WebVolts calculations. The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): The voltage V in volts (V) is equal to the power P in watts (W) divided by the current I in amps (A): The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω):
