What do you immediately notice about the bulbs that are different than the first configuration?
Measure the current in each of the two loops of the circuit.
The current is A in the first loop.
The current is A in the second loop.
Figure 2
Are the bulbs in Figure 2 connected in a series or a parallel circuit?
12. Using a voltmeter measure the voltage around each of the light bulbs.
The voltage of the first light bulb is V
The voltage of the second light bulb is V
Connect another bulb in parallel with the first two. Change the properties of this bulb to have 5 Ohms of resistance.
Using an ammeter measure the current in each of the three loops of the circuit.
The current is A in the first loop.
The current is A in the second loop.
The current is A in the third loop.
How has the current changed when adding another bulb in parallel?
Using a voltmeter measure the voltage around each of the light bulbs.
The voltage of the first light bulb is V
The voltage of the second light bulb is V
The voltage of the third light bulb is V
How has the voltage changed when adding another bulb in parahek?
