Figure shows the part of a circuit. Calculate the power dissipated in `3omega` resistance. What is the potential difference `V_C-V_B?`

The figure shows part of certain circuit, find, a. power dissipted in 5Omega resistance, b.Potential difference V_C-V_B c.Which battery is being charged?

The power dissipated (in watt) in 3Omega resistance in the following circuit is

In the circuit of figure, the current in 4Omega resistance is 1.2A , what is the potential difference between B and C?

In the circuit shown the cell is idea with end =15V each resistance is of 3Omega The potential difference the capacitor is

On giving 220 V to a resistor the power dissipated is 40 W then value of resistance is

A voltmeter of resistances 400(Omega) is used to measure the potential difference across the 100(Omega) resistor in the circuit shown in figure.(a) What will be the reading of the voltmeter ?(b) What was the potential difference across 100(Omega) before the voltmeter was connected ?

The power dissipated in the circuit shown in the figure is 30 W. The value of R is -
