Solution
The correct option is A zero
In a circuit having some resistance R and a voltage supply V , let Current I = 0 then voltage drop across resistor = I*Rso If there is no current, voltage drop across a resistor will be zero. So, voltmeter reading will be zero.
In a circuit having some resistance R and a voltage supply V , let Current I = 0 then voltage drop across resistor = I*R
so If there is no current, voltage drop across a resistor will be zero. So, voltmeter reading will be zero.
