Lab 5: Pre-Lab Questions (40) 1. A circuit has three resistors connected to a 3.00-V battery in series: R1 = 15.0 01, R2 = 10.0 02, and R3 = 25.0 0. Find the equivalent resistance, Req, the total current in the circuit, Itot, and the voltage across EACH resistor, Vi, V2, and V3. (10 pts. total - 2 pts. each) 2. The same resistors are now connected to the 3.00-V battery in parallel. Find the equivalent resistance, Req, the total current in the circuit, Itot, and the current through EACH resistor, I1, 12, and 13. (10 pts. total - 2 pts. each) 52 MW R R2 MM R3 R4 3. A fourth resistor, R4 = 13.0 0, is now added, and the four resistors are arranged according to the diagram above. Find the equivalent resistance, Req, the total current in the circuit, Itot, the current through EACH resistor, I1, I2, 13, and I, and the voltage across EACH resistor, V1, V2, Va, and Vi.
