Answer:
power = 142.4 W
Explanation:
power of heater in Germany (P₁) = 523.2 W
power of heater in America (P₂) = ?
outlet voltage in Germany (V₁) = 230 V
outlet voltage in America (V₂) = 120 V
- While in Germany, power =
523.2 =
R = 101.1
- While in America, also power =
using the value of R gotten above
power =
power = 142.4 W
