Question

If 10 Volt is applied across 20 ohm resistance then how much current will flow through resistor? *

Answer 1

Answer:

V = I × R

given , V = 20 volts R = 20 ohms

I = V/R

= 10/20

= 0.5 amps or 500 ma

Answer 2

Given,

10 volt is applied across 20 ohm resistance.

To Find,

How much current will flow through the resistor?

Solution,

We can solve the question as follows:

It is given that a voltage is 10 V is applied across a resistance of 20 ohms. We have to find the current through the resistor.

$Voltage = 10\: V$

$Resistance = 10\: ohms$

According to Ohm's Law, the voltage applied across a conductor is directly proportional to the resistance through it.

$V$∝$R$

Removing the proportionality constant,

$V = IR$

Where, $I = Current$

Now, to find the current, we will substitute the values in the above formula,

$10 = I*20$

$I = \frac{10}{20}$

$I = 0.5\: Amperes$

Hence, the current through the resistor is 0.5 A.
