\huge {\underline{\pink{Given:-}}}

  • Potential Difference ,V = 220V
  • Resistance ,R = 1200Ω
  • Resistance of Heater Coil = 100Ω

\huge {\underline{\blue{To Find:-}}}

  • Current in both Case ,I

\huge {\underline{\green{Solution:-}}}

Using Ohm's Law

• V = IR

Where,

V is the Voltage

I is the Current

R is the resistance.

For Bulb

V = IR

Substitute the value we get

➺ 220 = I × 1200

➺ I = \frac{220}{1200}

→ I = 0.18 A

Therefore, the current flow in the bulb is 0.18 Ampere.

For Electric Heater

V = IR

➺ I = \frac{V}{R}

Substitute the value we get

➺ I = \frac{220}{100}

➺ I = 2.2 A

Therefore, the current flow in the bulb is 2.2 Ampere.

Answer:

[ Question 1 ]

Given :

  • Voltage= 220V.

  • Resistance = 1200Ω.

To Find :

  • How much current will an electric bulb

Solution :

Concept :

  • Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

follow !me

Current (I) = Voltage (V)/ Resistance (R).

Substitute all values :

I = 220V/1200Ω.

I = 11/60

I = 0.183 A.

Hence 0.183 A. current will an electric

[ Question 2 ]

Given :

  • Voltage= 220V.

  • Resistance= 100Ω.

To Find :

  • how much current will an electric heater call grow

Solution :

I = V/R.

Substitute all values :

I = 220V/100Ω.

I = 22/10

I = 2.2 A.

Hence 2.2 A. current will an electric heater call grow

more to know :

Current:

  • Electric current is expressed by amount of charge flowing through a cross section of a conductor in unit time.

Voltage :

  • Voltage also called the Potential difference is the measure of difference in charges at the two positive and negative ends of any cell or appliance.

Resistance :

  • Resistance in a conductor can be defined as the opposition offered to the flow of electrons.
