Question

If the resistance of an electric iron is 70 Ω and a current of 3.2 A flows through the resistance. Find the voltage between two points.

Answer 1

Given :-

Resistance = 70Ω

Current = 3.2A

To Find :-

Voltage

Solution :-

According to Ohm's law :-

$\bf V = IR$

• V denotes voltage
• I denotes current
• R denotes resistance

Substitute the values :-

$: \implies \sf V = 3.2 \times 70$

$: \implies \sf V = 32 \times 7$

$: \implies \sf V = 224$

Voltage between two points = 224V

Answer 2

Answer:

Given :-

• The resistance of an electric iron is 70 Ω and a current of 3.2 A flows through the resistance.

To Find :-

• What is the voltage between the two points.

Formula Used :-

$\clubsuit$ Voltage Formula :

$\mapsto \sf\boxed{\bold{\pink{V =\: IR}}}$

where,

• V = Voltage
• I = Current
• R = Resistance

Solution :-

Given :

$\bigstar\: \: \bf{Current =\: 3.2\: A}$

$\bigstar\: \: \bf{Resistance =\: 70\: \Omega}$

According to the question by using the formula we get,

$\longrightarrow \sf\bold{\purple{Voltage =\: Current \times Resistance}}$

$\longrightarrow \sf Voltage =\: 3.2 \times 70$

$\longrightarrow \sf Voltage =\: \dfrac{32}{10} \times 70$

$\longrightarrow \sf Voltage =\: \dfrac{32 \times 70}{10}$

$\longrightarrow \sf Voltage =\: \dfrac{224\cancel{0}}{1\cancel{0}}$

$\longrightarrow \sf Voltage =\: \dfrac{224}{1}$

$\longrightarrow \sf\bold{\red{Voltage =\: 224\: Volt}}$

${\small{\bold{\underline{\therefore\: The\: voltage\: between\: the\: two\: points\: is\: 224\: Volt\: .}}}}$
