Project #16

OBJECTIVE: To compare types of circuits.

When More Are More

Build the circuit and connect the jumper wires

as shown. The LED•(D4) will be on but the

resistor is limiting the electricity through it.

Turn on the switch (S1) to place three other

resistors in

parallel

with the first one. This

increases the flow of electricity to the LED, and

makes it brighter. Placing other resistors in

parallel reduces the total resistance (to 250Ω

here), so more are less.

Build the circuit and connect the jumper wires as

shown. The LED•(D4) will be on but the four

resistors are limiting the electricity through it.

Turn on the switch (S1) to bypass three resistors

that are in

series

with the first one. This

increases the flow of electricity to the LED, and

makes it brighter. Placing other resistors in

series increases the total resistance, so more

are more.
