Question

a. Calculate the power output of 2A current in a device with a resistance of 115Ω.

b. Calculate the heat generated if this device is operated for 5 minute.

Pls answer fast​

Answer 1

Answer:

Given: Resistance of appliance = 115 ohm. Current = 2A.

To find: Power.

Solution: Using ohms law.

V = I × R. Where. V : potential difference. I : current. R : resistance. V = 115 × 2.

V = 230 V. Now , we know that.

P = V × I. Where. P : power. V : already given. I : already given. P = 230 × 2.

P = 460 W.

Hence , power = 460 W.

Answer 2

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion
