Enter the values of voltage, V(v), current, I(A) and time, t(s) to determine the value of Electrical work, We(J).
Electrical Work Formula:
Electrical Work is a fundamental concept in both physics and electrical engineering, defining the work done by an electric current over a period of time.
This measurement is crucial for understanding how much energy is transferred by the current, which is vital for designing and operating electrical systems efficiently.
Electrical work is directly related to power consumption and is an integral factor in fields ranging from household electricity usage to large-scale industrial power management.
Electrical work, We(J) in joules is calculated by the product of voltage, V(v) in volts, current, I(A) in amperes and time, t(s) in seconds.
Electrical work, We(J) = V(v) * I(A) * t(s)
We(J) = electrical work in joules, J.
V(v) = voltage in volts, V.
I(A) = current in ampers, A.
t(s) = time in seconds, s.
Electrical Work Calculation:
- Calculate the electrical work done by a household appliance:
Given:
-
- Voltage, V(v) = 120 volts
- Current, I(A) = 10 amperes
- Time, t(s) = 3600 seconds (1 hour)
Electrical work, We(J) = V(v) * I(A) * t(s)
We(J) = 120 * 10 * 3600
We(J) = 4320000J.
- Determine the time for charging an electric vehicle:
Given:
-
- Voltage, V = 240 volts
- Current, I = 20 amperes
- Electrical work, We(J) = 25920000 Joules
Electrical work, We(J) = V(v) * I(A) * t(s)
t(s) = We(J) / V(v) * I(A)
t(s) = 25920000 / 240 * 20
t(s) = 5400s.
