Capacitors

In this task we had  to wire up a capacitor with a resistor in series.
A capacitor stores electrical charge , it provents voltage spikes from happening.

Relays

A relay is the component which uses a low amps in a circuit to switch on a greater amp circuit.

We measured resistance of the relay from
86 to 85 was 69.8 ohm
30 to 87a was 0.2 ohm
30 to 87 was infinity (∞)


When the relay is off 30 to 87a is Normally Closed and 30 to 87 is Normally Open

Resistors

 

RESISTORS

We had  to choose 6 type of resisitors, then using the resistor colour band  and using the chart bellow we  found out the resistance of the resistors in Ohm's(Ω), and checking the resistors tolerance, then using a multimeter to check that the calculations we did were correct . Then we took two resistors and wired them into series to meausure the total resistance of the resistors in series, then we wired them up into parallel to and measure the resistance and the total resistance should be lower than the lowest resistance because more consumers are added into a parallel cicuit and the resistance goes down and the current goes up, but in the series circuit they only have one path to follow because they go through all the resistors creating higher resistance making less current flow.
