Question

internal resistance of a cell of 1.5 volt is o.5 ohm .What is the maximum current that can be obtained by this cell​

Answer 1

Answer:

V= IR

I= V/R

I= 1.5/0.5

I= 15/5=3 ampere

Answer 2

Given,

The internal resistance of a cell of 1.5 volts is o.5 ohm.

To Find,

The maximum current that can be obtained by this cell​ =?

Solution,

We can solve the question as follows:

It is given that the internal resistance of a cell of 1.5 volts is o.5 ohm. We have to find the maximum current that can be obtained by this cell.

$Internal\: resistance = 0.5\: ohms$

$Voltage = 1.5\: V$

According to Ohm's Law, the voltage through a conductor is directly proportional to the current through the same conductor.

$V$∝ $R$

Removing the proportional sign,

$V = IR$

Where, $I = Current$

Now,

To find the maximum current, we will substitute the given values in the above formula,

$1.5\: V = I*0.5$

$I = \frac{1.5}{0.5}$

$I = 3\: A$

Hence, the maximum current that can be obtained by this cell​ is 3 A.
