 2007 B3 Printer Friendly Version The circuit above contains a battery with negligible internal resistance, a closed switch S, and three resistors, each with a resistance of R or 2R.

(a) Currents

 i. Rank the currents in the three resistors from greatest to least, with number 1 being greatest. If two resistors have the same current, give them the same ranking. (b) Voltages

 i. Rank the voltages across the three resistors from greatest to least, with number 1 being greatest. If two resistors have the same voltage across them, give them the same ranking. For parts (c) through (e), use = 12 V and R = 200 ohms.

 (c) Calculate the equivalent resistance of the circuit.

 (d) Calculate the current in resistor Rc.

 (e) The switch S is opened, resistor RB is removed and replaced by a capacitor of capacitance 2.0 x 10-6 F, and the switch S is again closed. Calculate the charge on the capacitor after all the currents have reached their final steady-state values. Topic Formulas Related Documents
