The figure below shows a battery connected to a circuit. The potential difference across the battery and the resistance of each resistor is given in the figure. PLESE I NEED HELP ON THESE.

The figure below shows a battery connected to a circuit. The potential difference across the battery and the resistance of each resistor is given in the figure. 7.60 0 4.00 Q 7.60 0 4.00 Q 4.00 Q 2.00 Q 12.0 0 WW + 23.0 V A What is the current (in A) in the 12.0 Q resistor?Consider the series RC-circuit shown below for which R = 52.5 kQ, C = 36.0 JF, and & = 16.0 V. Find the following. C + E R S A (a) the time constant of the circuit S (b) the charge on the capacitor one time constant after the switch is closed C
