Question

pls help me can you pls​

Answer 1

Answer:

Voltage = 230 volts

Current = 2 Amperes

Time = 2 minutes

1 minute = 60 seconds

2 minutes = 2 x 60 = 120 seconds

To find:

Heat produced

We can say that:

heat = I²RT (or) VIT

Solving with I²RT:

R=\frac{V}{I}R=

I

V

R=\frac{230}{2}R=

2

230

R = 115 \ ohmsR=115 ohms

Substituting the values,

2²×115×120

= 55200 joules

Using VIT :

=230×2×120

=55200 Joules

The heat produced is equal to 55200 joules
