Answer:

The formula To calculate current (I) when power (P) and potential difference (V) are given us :

  • I = P/V

We are given :

  • Power = 440 Watts
  • Potential difference = 220 V

Substitute the given values

I = 440/220

I = 2 Amperes

Now we can use ohm's law to calculate the resistance

  • V = IR
  • R = V/I

Substitute the required values

R = 220/2

R = 110 ohm

Therefore,

  • Electric current (I) = 2 amperes
  • Resistance (R) = 110 ohm

Final answer:

The electric current is 2 Amperes and the resistance is 110 Ohms.

Explanation:

To calculate the electric current and resistance, we can use the formula:
I = P/V
where I is the electric current, P is the power consumption, and V is the potential difference.
Given that the power consumption is 440 watts and the potential difference is 220V, we substitute these values into the formula:
I = 440/220

= 2 Amperes

To calculate the resistance, we can use Ohm's law:
R = V/I
where R is the resistance. Substituting the values of V and I:
R = 220/2

= 110 Ohms
