The resistance of the wire to the nearest tenth of an ohm is 2Ω.
We know that ,
Potential difference (V) = current (I) * Resistance (R)
V = IR
I = 2.0A
V = 10v
So the
R = ?
V = IR
R = V / I
R = 10 / 2
R = 2Ω
Thus the resistance across the wire is 2Ω.
Resistance is a measure of the opposition to current flow in an electrical circuit. resistance always measure in ohm.It design with R.A resistor is a device designed to produce resistance. resistor can be used to the limit current, divide voltage, or generate heat.
