Question
A 3 V battery is connected in series with ammeter and 2 ohm resistance after short circuiting. What will be the reading of ammeter?
Options
- A
1 A
- B
1.5 A
- C
5 A
- D
6 A
Explanation
Given:
Voltage = V = 3V
Resistance = R = 2Ω
Current = I = ?
As we know that:
V = IR
I = V / R
= 3 / 2
I = 1.5 A
