Question

if 5 volt current flow in a conductor then produces 110V P.d. then find the amount of current if p.d. produce 200 volt​

Answer 1

$\LARGE{\bf{\underline{\underline{GIVEN:-}}}}$

• Current (I) = 5 A
• Initial Voltage/Potential difference (V) = 110 V.
• New Voltage/Potential difference (V' ) = 200 V.

$\LARGE{\bf{\underline{\underline{TO:FIND:-}}}}$

• The amount of current if voltage is  200 V.

$\LARGE{\bf{\underline{\underline{SOLUTION:-}}}}$

▣ Lets first calculate the resistance.

$\to \sf{\red{R=\dfrac{V}{I} }}$

Where:

• R - Resistance.
• V - Voltage.
• I - Current.

▣ Substitute the values.

$\sf \to R=\dfrac{110}{5}$

$\leadsto \sf{\green{R=22 \Omega}}$

▣ Now, the resistance is constant, but the voltage changes to 200 V.

New current:

$\to \sf{\red{I'=\dfrac{V'}{R} }}$

Where:

• I' - New current.
• V' - New voltage.

▣ Substitute the values.

$\to \sf I'=\dfrac{200}{20}$

$\leadsto \sf{\green{I'=9.09 A}}$

∴Amount of current if voltage is 200 V is 9.09 A.
