Question

An electric circuit consisting of a battery of five 2V cells, a 20 ohms resistor , a key in series.
Calculate the value of current flowing through 20 ohms resistor.

Answer 1

Hi friend, Here the required answer:-

Resistance (R)= 20 Ohms
Voltage (V) = 2×5= 10 Volts
Current (I) = V/R= 10/20= 1/2= 0.5 Ampere.

Hope this helps you...

Answer 2

Hi friend ,

V = 2 ×5 = 10 V
R = 20 ohms

V= I×R

10 = I×20

10/20 = I

0.5 A

====================
Hope this helped u...
