Solution: The result of I needs to be multiplied by 1000 before it is displayed, and the A unit needs to be updated to mA. Retest the numbers in the activity, and verify that the results are 5.4545… mA and 1.2 mA.
# calculate_i_in_ma_from_v_and_r from microbit import * while True: text = input("Enter volts: ") V = float(text) text = input("Enter ohms: ") R = float(text) I = V / R I = I * 1000 # <-- Add print("I = ", I, "mA") # <-- Modify print()
