Answer 3

Is the force and electron flow in a motion.

Question 4

POWER

Answer 4

The rate w/c work is done.
- it consume in a resistor.
- symbol ( P ).
- power measure in watts ( W ).

Question 5

WATTS

Answer 5

Rate work is done in a circuit.
- 1 amp flow w/ 1 volt applied.

Question 6

POWER FORMULA;

Answer 6

Voltage times current:
P = E× I
Or
P = EI

Power substitute by Ohms Law:
P = I²R
And
P = E²_
R
