Question

Draw a diagram of a circuit constiting of battery of three cells 2V,3V, 5V, and 5 ohm, 8 ohm, 12 ohm, 7 Ohm and a plug key all collected in series . Calculate the current through the circuit

Answer 1

total voltage = 2+3+5= 10 V

total resistance = 5+8+12+7 = 32

current = V/R = 10/32 = 0.3125

Answer 2

Total Resistance = 5+8+12+7=32R
Total voltage = 2+3+5=10V
Now,
V = IR
10 = I×32
I = 10/32
I = 0.3125 A
Hence, Current is flowing in circuit = 0.3125 A
