2. Series circuit

(a) Choose a battery voltage and design a circuit with two different resistors connected in series.

(b) Calculate the total current and the voltage drop across each resistor.

(c) Using the voltmeter and ammeter, measure the total current in the circuit and the voltage drops across the resistors. When a voltmeter is used to measure voltage differences, it is always connected in parallel across a circuit element. When an ammeter is used to measure current, it is always connected in series with a circuit element. Compare the measured values to the values you calculated.

3. Parallel Circuit

(a) Choose a battery voltage and design a circuit with two different resistors connected in parallel.

(b) Calculate the total current and the current through each resistor.

(c) Using the ammeter, measure the total current and the current through each resistor.  Compare the measured values to the values you calculated.
