Question

The resistance of a metal is given by R = V/I, where V is potential difference
and I is the current. In a circuit the potential difference across resistance is V =
(10 + 0.5) V and current in resistance is given by 1 = (2 +0.2) A. What is the
value of resistance in a with percentage error?​

Answer 1

ᎯᏁᏕᏯᎬᏒ

$\boxed</strong><strong>{</strong><strong>\</strong><strong>p</strong><strong>u</strong><strong>r</strong><strong>p</strong><strong>l</strong><strong>e</strong><strong>{ \rm{Resistance~(R) = \frac{Potential~Difference~(V)}{Current~(I)}}</strong><strong>}</strong><strong>}$

$\rm \: R = \frac{10 + 0.5}{2 + 0.2}$

$\rm R = \frac{10.5}{2.2}$

$\rm </strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{</strong><strong>R = 4.77 \Omega</strong><strong>}</strong><strong>$

Answer 2

Answer:

Given:-

Voltage (V) = 10.5V

Current (I) = 2.2Amp

To find:-

Resistance

By applying, R = V/I

= 10.5/2.2

= 4.772727ohm.
