Redraw the circuit of Question (Draw a schematic diagram of a circuit consisting of a battery of three cells of \(2\ V\) each, a \(5\ Ω\) resistor, an \(8\ Ω\) resistor, and a \(12\ Ω\) resistor, and a plug key, all connected in series), putting in an ammeter to measure the current through the resistors and a voltmeter to measure the potential difference across the \(12\ Ω\) resistor. What would be the readings in the ammeter and the voltmeter?
An ammeter is connected in while the voltmeter is connected in to the resistor.
Total resistance of the circuit \(=\)
Potential difference of the circuit \(=\)
The current flowing through the circuit is calculated by the formula
Potential difference across \(12\ Ω\) resistor is
