Book Free DemoIn the circuit diagram given below, three resistors \(R_1\), \(R_2\) and \(R_3\) of \(5\ Ω\), \(10\ Ω\) and \(20\ Ω\), respectively are connected as shown.
Circuit diagram
Calculate,
(a) Current through each resistor
(b) Total current in the circuit
(c) Total resistance in the circuit
(b) Total current in the circuit
(c) Total resistance in the circuit
(a) Since the resistors are connected in parallel, the potential difference across each resistor is same (i.e. \(V = 10V\)). Therefore, the current through each resistor is calculated by the formula,
Current through \(R_1\) \(=\) \(A\)
Current through \(R_2\) \(=\) \(A\)
Current through \(R_3\) \(=\) \(A\)
(b) Total current in the circuit,
On substituting the known current values, we get
\(=\) \(A\)
(c) Total resistance in the circuit,
On substituting the known values, we get
\(=\)
