Study Notes
Energy Stored in an Inductor
- The energy stored in an inductor is calculated using the formula: Energy (E) = 1/2 * L * I^2
- E represents Energy in Joules (J)
- L represents Inductance in Henries (H)
- I represents Current in Amperes (A)
Inductance Calculation
- A 50 mH coil is equivalent to 0.05 Henries (H).
- 1 mH (millihenry) = 0.001 H (henry)
Energy Stored in a 50 mH Coil
- The energy stored in a 50 mH coil carrying a current of 2 amperes can be calculated using the formula:
- E = 1/2 * 0.05 H * (2 A)^2
- E = 0.1 Joules (J)
Incorrect Inductance Conversion
- The text does not provide specific values for inductance conversions. It simply asks which value is incorrect.
- To determine the incorrect value, you would need to be provided with a set of options.
Components Not Affecting Energy Stored
- The energy stored in a coil depends solely on the values of Inductance (L) and Current (I).
- Other components, such as resistance, do not influence the energy stored in the coil.
