QUESTION
Calculate the resistance if
V
=
24
V
V = 24 \text{V}
V
=
24
V
and
I
=
3
A
I = 3 \text{A}
I
=
3
A
.
QUESTION
Find the equivalent resistance of
R
1
=
6
Ω
R_1 = 6 \text{Ω}
R
1
=
6
Ω
and
R
2
=
3
Ω
R_2 = 3 \text{Ω}
R
2
=
3
Ω
in parallel.
QUESTION
Find the current if
V
=
12
V
V = 12 \text{V}
V
=
12
V
and
R
=
4
Ω
R = 4 \text{Ω}
R
=
4
Ω
.

ANSWER
I
=
3
A
I = 3 \text{A}
I
=
3
A
. Using
V
=
I
R
V = IR
V
=
I
R
, so
I
=
V
/
R
=
12
/
4
I = V/R = 12/4
I
=
V
/
R
=
12/4
