Answer:
Maximum voltage = 5 V
Explanation:
The maximum power from the resistor is evidently 0.03125W in the time periods given.
And Power dissipated from electric circuits is given by
P = IV
V = IR
P = I(IR) = I²R
Since I = (V/R), power can also be expressed as
P = IV = (V/R)V = V²/R
Since the resistance of the resistor isn't variable, then the variable here has to be the voltage, So, to calculate maximum voltage,
R = 800 ohms, P = 0.03125 W
0.03125 = V²/800
V² = 25
V = 5V
In this exercise we have to use the knowledge of voltage to calculate its final value, so we have to:
The value Maximum voltage = 5 V
Recalling some formulas used to calculate the voltage of a resistor we have that:
[tex]P = IV\\V = IR\\P = I(IR) = I^2R\\I = (V/R)\\P = IV = (V/R)V = V^2/R[/tex]
They are putting the values that are already known in the formulas is:
- R = 800 ohms
- P = 0.03125 W
We have that will be equal to:
[tex]0.03125 = V^2/800\\V^2 = 25\\V = 5V[/tex]
