Final answer:
The power for element a is 60 W.
Step-by-step explanation:
To find the power for element a, we can use the equation P = IV, where P is the power, I is the current, and V is the voltage. In this case, if the ammeter reading is 2 A and the voltmeter reading is 30 V, we can substitute these values into the equation to get:
P = (2 A)(30 V) = 60 W
