Given,Inductance, L = 0.50 HResistance, R = 100 ΩEffective voltage, Ev = 240 VFrequency of the ac supply, f = 50 HzWe can calculate,Angular frequency, ω = 2πf = 100 πPeak voltage, E0 = 2 Ev = 2 ×240 V(a) Maximum amount of current in the coil is given by, I0 = E0R2+ω2L2 =2 × 240104+(100π ×0.5)2 = 1.82 A (b) In LR circuit,If , E = E0 cos ωt then, I = I0 cos (ωt-ϕ) Now, At t = 0, E. Consider a practical case of a coil in parallel with a condenser, as shown in Fig. 6.8. Let the coil be of resistance R ohms and inductance L henrys and the condenser of resistance R ohms and capacitance C farads. Such a circuit is said to be in electrical resonance when the reactive (or wattless) component of line current becomes zero

and obtain the photon energy in units of eV for different parts of the electromagnetic spectrum. In what way are the different scales of photon energies that you obtain related to the sources of electromagnetic radiation? Answer: Given: Energy of photon E = (h (c/ λ)) Where, h = (6.63 x 10-34) js and c = (3 x 10 8) m/s, λ = wavelength of. An electronic circuit component that has the ability to store and electrical charge. The formula used to determine capacitance is C = Q/V where C is capacitance in farads, Q is the quantity of stored electrical charge in coulombs, and V is voltage. Therefore, stored electric charge can be calculated using the formula: Q = CV

capacitance - electronics tutorial

C = 3.3 F In parallel: C = C 1 + C 2 C = 10 + 5 = 15 F. 8. (moderate) If the two capacitors in question #7 were connected to a 50 volt battery determine the voltage across the capacitors for each connection type. For the series connection: The charge on each capacitor is the same as the charge on the effective capacitance. C = Q/V 3.3 = Q/50 Q. 3 . Capacitance and dissipation factor (DF) measured under the following conditions: 1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF 120 Hz ±10 Hz and 0.5 ±0.1 Vrms if capacitance > 10 µF. 4 . To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits
