1. (a) Determine the equivalent resistance between points a and b. (b) Find the power across the 8.50 resistor if the voltage between points a and b is 30 V. Draw the circuit as you go. See image below 2. The current l1 in the following circuit has a value of 1.20 A. (a) Using Kirchhoff's laws, find the currents I2 and I3. (b) Find the power across the 15.0 resistor. See image below 3. In a series RC circuit, the resistor has a value of 20.0 k , the capacitor has a capacitance of 10 nF, and they are connected to a 20.0 V source. (a) Determine the time constant t (b) The circuit it has been connected for a long period of time and at t=0 it is disconnected from the voltage, leaving only the capacitor and resistor connected in series. Determine the time it takes for the capacitor to discharge to 30% of its initial value
