Final answer:
The current flowing through the small electrical heater from a 12V supply is 5A.
Step-by-step explanation:
Given power (P) = 60W and voltage (V) = 12V, we can determine the current (I) flowing through the heater using the formula P = IV. Rearranging the formula to solve for I gives us I = P/V.
Substituting the given values, we have I = 60W / 12V = 5A.
Therefore, the current flowing through the heater is 5A.
