ohm parallel resistance is equivalent to a
voltage source of
volt and
series resistor *
O 3
15 Volt and 3 ohm
O 45 volt and 3 ohm
ОООО
O 5 volt and 0 ohm
45 volt and 0 ohm​

Answer 1

GiveN :-

• There's a resistance of 3Ω and the current is 15A .

To FinD :-

• The voltage source .

SolutioN :-

There's a resistance of 3Ω through which a current of 15A is flowing . We need to find the voltage source. Here we can use Ohm's Law to find out the Voltage .

★ According to the Ohm's Law :-

$\sf:\implies \pink{ Voltage = Current\times Resistance } \\\\\sf:\implies V = 15A \times 3\Omega \\\\\sf:\implies \underset{\blue{\sf Required\ Voltage}}{\underbrace{\boxed{\pink{\frak{ Voltage= 45 \ Volts . }}}}}$

$\rule{200}2$

$\underline{\sf:\implies \gray{ More \ To \ Know }}$

Ohm's Law establishes a Relationship between the Current , Resistance and Potential Difference.

According to Ohm's Law if physical conditions such as temperature remains constant then the potential difference applied across the end of the conductor is directly proportional to the electrical current flowing through it.

$\sf:\implies V \propto I \\\\\sf :\implies \pink{ V = I R }$
