The amount of current is based on the supply voltage and the resistance in the circuit. As a result, one watt will be equal to the volt-ampere result of one-volt times one-ampere (one watt is the rate of consuming energy at one joule per second). Alternating current flowing through a coil is opposed by two factors, resistance (R) and inductive reactance (XL). In this circuit, the total resistance is load resistance so the R = 2 and the input voltage supply is 12V DC so the V = 12V. Passive components in the circuit consume electrical energy. The electrons in a wire carrying direct current move slowly, but eventually they travel from one end of the wire to the other because they keep plodding along in the same direction. Step 2: Circuits. 39. Next we calculate the amperage in the circuit: I = V / RT = 12V / 10 Ohms = 1.2 Amp.
