Measure the Voltage of a battery. What size is it suppose to be? What was your reading?
Choose three random resistors and measure their resistance.
Hold one probe between your thumb and forefinger on each hand, measure and record the resistance of your body between your hands.
Considering that a current of 100-200 mA through your heart will probably kill you, how much voltage across your hands would be lethal?
What is the Voltage across BA (V
BA
)? Pay attention to the way the multimeter is hooked up to the circuit.
Look at the following 3 circuits. In each, the multimeter is connected to measure the voltage drop across the battery. Compare the voltage measurements for V
XG
, V
YG
and V
ZG
to the voltage of the batteries. Are they the same?
Yes
No
In the circuit below, the multimeter is set to measure the voltage drop across three batteries. Add the battery voltages for each path, taking into account the polarity of the batteries. What is the voltage reading in this circuit?

What is the current between A and B?
An unknown resistor is attached to a 12-volt battery. The current is 1.2 amps. What is the resistance?
