Answer:
See the answers below.
Step-by-step explanation:
a)
The dryer plate indicates that the estimated power is 1500 [W] and operates connected to the mains with an electrical voltage of 220 [V]
b)
The electrical current is determined by the following expression:

where:
V = voltage = 220 [V]
I = current [amp]
P = power [W]
![1500=220*I\\I=6.81[amp]](https://img.qammunity.org/2022/formulas/physics/high-school/2n0m3ifvbgupvi2xib4j4ikdp8jis4b2tb.png)
