Answer:
P = 1.44 Watts
Step-by-step explanation:
We know that the relation between voltage and current in a simple circuit with a resistor is
V = I.R
Where
V = the voltage of the source
I = current of the circuit
R = resistance
The power is defined as
P = V.I
Which is the same as
P = V.(V/R)
P = (24 v)^2 / (400 ohm)
P = 1.44 Watts
<span>To put the unknown in other words, we are to determine a fraction that has a denominator of 10 which should be equivalent to 3/5. If we let x be the numerator of the second fraction such that we form a proportion out of the two fractions that is,
3/5 = x/10
The value of x is calculated as below,
x = (3)(10) / 5 = 6
