Question

Three resistors are connected in series with resistance 10 ohms , 3 ohms and 20 ohms. The current through the circuit is 0,3A. Calculate the total resistance and voltage across the series connection

Answer 1

I = 0.3 A

R = R1 + R2 + R3

= 10 + 3 + 20

= 33 ohm

Total Resistance = 33 ohm

V= IR

= 0.3 × 33

= 9.9 v
