1) A circuit contains three resistors connected in series across 100 volts; the circuit
current is 2 Amperes. Two resistors (R1 and R2) have known values of 5 and 10 ?,
respectively. Determine:
a. The resistance of the entire circuit.
b. The resistance of the third resistor R3.
c. The voltage drop across each resistor.
2. You are given a spotlight which takes 2 amperes of current designed to work off
a 6-volt battery. If the available source is a 12-V battery, what values of resistance
would you need to connect in series with the spotlight before you could safely
switch it on? Draw the circuit diagram and show the values of voltages and
currents.
