Question

In an electrical circuit, the current is related to the power and resistance according to the rule I=pR−−√, where I represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms). What is the electrical power drawn by a device that has a resistance of 15 ohms with a current of 4 amps?

Answer 1

Answer:

$P=0.27\,\,watts$

Step-by-step explanation:

Consider the formula: $I=PR$

Here, $I$ represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).

Resistance = 15 ohms

Current = 4 amps

To find electrical power drawn by a device, put $R=15\,,\,I=4$

So,

$4=15P\\P=\frac{4}{15}=0.27\,\,watts$
