Figure shows a part of an electric circuit. The potentials at points \( a, b, \text{and} \, c \) are \( 30 \, \text{V}, 12 \, \text{V}, \, \text{and} \, 2 \, \text{V} \), respectively. The current through the \( 20 \, \Omega \) resistor will be:
In the following circuit, the magnitude of current $I _1$, is ______ A
In the circuit shown in figure, the potential difference between points A and B is 16 V. The current passing through \( 2 \Omega \) resistance will be
Three voltmeters \( A \), \( B \), and \( C \) having resistances \( R \), \( 1.5R \), and \( 3R \), respectively, are connected as shown. When some potential difference is applied between X and Y, the voltmeter readings are \( V_A \), \( V_B \), and \( V_C \) respectively. Then:
