Electrical work can be calculated using the formula: W = V * Q, where W stands for work (measured in joules), V is the voltage (volts), and Q is the charge (coulombs). Another common formula used is W = P * t, where P is power (watts) and t is time (seconds).

FAQs & Answers

  1. What is the formula for electrical work? The primary formulas for electrical work are W = V × Q, where W is work in joules, V voltage in volts, and Q charge in coulombs; and W = P × t, where P is power in watts and t is time in seconds.
  2. What units are used in calculating electrical work? Electrical work is measured in joules (J), where voltage is in volts (V), charge in coulombs (C), power in watts (W), and time in seconds (s).
  3. How is electrical power related to electrical work? Electrical power (P) multiplied by time (t) gives electrical work (W), expressed as W = P × t.
