3 FUNDAMENTALS OF ELECTRICITY
Part 2
Lower Resistance Equates To Higher Current
1.
The circuit in figure 4-2 will show that if a path becomes “easier” more current will flow through it. Build this circuit.

Turn on the DC supply and set it at 12 V. Note how bright the lamps are.
Remove L2 and L3 and reconnect the circuit as in figure 4-3.

3.
Turn on the DC supply and note how bright L1 is now. L1 should be much brighter now since the path has been streamlined by removing L2 and L3.
