It is part of a electrical circuit that provides the voltage needed to force current through the circuit. One example is our BATTERY or BATTERIES.
Load
Control Device
Supply or Source
Conductors
If the total resistance in the circuit is 9 Ohms and its source has 4.5 V. How much amount of electric current is flowing through the wire?
0.5 A
0.4 A
0.6 A
1.5 A
How much amount of force pushes the electrons through the circuit that has 2 batteries/supply?
1 battery = 1.5 V
(a)
A device is connected to a 330 V power supply line. If it draws a current of 0.5 A, calculate its power.
(a)
What kind of circuit is being described:
the current only takes one or single path for electrons?
Series Circuit
Parallel Circuit
Check the statements that described parallel circuit.
More than one path for current to flow
Voltage is the same across each branch
Voltage is reduced by each resistance – voltage drop
Total resistance goes down
