An open circuit containing five resistors starts at point a and ends at point b. The circuit extends to the right from point a and splits into two parallel horizontal branches. There is a 12.0 Ω resistor on the top branch and a 6.00 Ω resistor on the bottom branch. The branches then recombine and the circuit extends to the right to a 5.00 Ω resistor. To the right of the 5.00 Ω resistor, the circuit again splits into two parallel horizontal branches. There is a 4.00 Ω resistor on the top branch and an 8.00 Ω resistor on the bottom branch. The branches then recombine and the circuit extends to the right until it reaches point b.

The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Cil
