Answer:
The current is 4.2 amp.
(c) is correct option.
Step-by-step explanation:
Given that,
Power = 500 watt
Voltage = 120 Volt
Time = 30 sec
We need to calculate the current
Using formula of current
![P =I* V](https://img.qammunity.org/2020/formulas/physics/high-school/h9cglb4jkrrzk5g7v2ng6yenagzsdkmsw0.png)
![I = (P)/(V)](https://img.qammunity.org/2020/formulas/physics/high-school/nmwg5b8cmiomvdzxktnpxc4cse41lgyvgf.png)
Where, I = current
P = power
V = voltage
Put the value into the formula
![I=(500)/(120)](https://img.qammunity.org/2020/formulas/physics/high-school/xj2s4nz4naez7m2tairf3mjvxwyyoe0tc2.png)
![I=4.2\ amp](https://img.qammunity.org/2020/formulas/physics/high-school/98lrh77wmmhy53588qdo51p548pn7l7rhk.png)
Hence, The current is 4.2 amp.
