When there is 12 mA of current through a 1.2 k
resistor, the voltage across the resistor is

Answer: Option
Explanation:
V = IR (Ohms Law)
= 12 X 10-3 X 1.2 X 10 3
= 12 X 1.2
= 14.4 V

12mA = 1.2 X 10^-2 A
1.2 Kohm = 1.2 X 10^3 oham
V = I X R
=1.2X10^-2 X 1.2x10^3
= 14.4
1.2 Kohm = 1.2 X 10^3 oham
V = I X R
=1.2X10^-2 X 1.2x10^3
= 14.4

Jay deep is wrong.
Here.
For mA=mega Ampere sp its belongs to 10^-3 A.

@Arun i think you are wrong...
See clearly he changed value 12 ma to 1.2 *10^-2.
Hope so you understand:)

12mA = 1.2 X 10^-2 A.
1.2 Kohm = 1.2 X 10^3 ohm.
V = I X R.
= 1.2X10^-2 X 1.2x10^3.
= 14.4.
1.2 Kohm = 1.2 X 10^3 ohm.
V = I X R.
= 1.2X10^-2 X 1.2x10^3.
= 14.4.

V = IR.
SO, V = 12/1000*1.2*1000 = 14.4V.
SO, V = 12/1000*1.2*1000 = 14.4V.

Arun it's milli ampere not mega ampere, 1.2*12 = 14.4v.

V = IR.
I = 12MA,
R = 1.2KILO OHMS,
1A = 1000MA.
What about 12ma,
1a * 12ma/1000ma,
= 0.012a.
1kilohms = 1000 ohms,
what about 1.2kilohms.
1000 ohm * 1.2kiloohms/1kiloohms = 0.0012 ohms.
= 1200.
1200 * 0.012 = 14.4v.
I = 12MA,
R = 1.2KILO OHMS,
1A = 1000MA.
What about 12ma,
1a * 12ma/1000ma,
= 0.012a.
1kilohms = 1000 ohms,
what about 1.2kilohms.
1000 ohm * 1.2kiloohms/1kiloohms = 0.0012 ohms.
= 1200.
1200 * 0.012 = 14.4v.

V = I × R.
V = 12 × 1200.
= 14.4V.
V = 12 × 1200.
= 14.4V.
