Question

8. A circuit has two electric bulb with internal resistances 20ohm and 20ohm, connected in parallel

across a battery unknown value. If a current of 2 ampere is flowing in the circuit, find the voltage

of the battery.​

Answer 1

Answer:

Explanation:

1/equivalent resistance =1/20+1/20

equivalent resistance= 10 ohm

v=ir (ohms law)

v= 2(10)= 20v

Answer 2

Answer:

good question very good question
