Discussion topic: 272. The instrument is powered by a 24V supply with an output power of 32W; what is the output current in amps? (Exact to two decimal places; points will be awarded for formulas and calculation steps)
The power calculation formula is P=UI; therefore, the current I is P/U = 32/24, which is approximately 1.33A
Solution: P=UI, I=P/U, I=32W/24V=1.33A
Formula: I=P/U; therefore, the current is 32/24, which equals 1.333 A
33W/24V=1.33A
Power = Voltage × Current； Current = Power ÷ Voltage ； Current = 32W ÷ 24V = 1.333A
Using the electrical power formula P=UI, it can be derived that I=P/U; therefore, I=32/24≈1.33A
