BASIC ELECTRONICS - OD1633 - LESSON 1/TASK 2
To solve the problem, a circuit diagram is first drawn and labeled (figure
24, on the following page).
R1 = 20 Ohms
R2 = 30 Ohms
R3 = 50 Ohms
I = 2 amperes
ET = E1 + E2 + E3
SOLVING FOR APPLIED VOLTAGE IN A SERIES CIRCUIT.
E1 = R1 x I1 (I1 = The current through resistor Rl)
E2 = R2 x I2
E3 = R3 x I3
ET = (R1 x I1) + (R2 x I2) + (R3 x I3)
ET = (20 Ohms x 2 amps) + (30 Ohms x 2 amps) + (50 Ohms x 2 amps)
