A. 36A
B. 0.6A
C. 4A
D. 0.25A​

Answer 1

Answer:

Explanation:

Given An electric lamp whose resistance is 20 Ohm and a conductor of 4 Ohm resistance are connected in series to a 6 V battery as shown in figure. Then the total current flowing through the circuit is

Given battery voltage V = 6 V

Resistance of electric lamp R1 = 20 ohms

Conductor of resistance in series R2 = 4 ohms.

So total resistance in the circuit R=

R1 + R2

=

20 + 4

= 24 ohms.

By using Ohm's law we have,

Current through the circuit I = V/

R

= 6/

24

= 1/4

By using Ohm's law we have,

Current through the circuit I = V/

= 6/

24

= 14

0.25 Amps

Therefore total current flowing through the circuit will be 0.25 Amps.
