Calculate the capacitance of a 2.3 mm diameter ceramic capacitor if the plates are separated by 0.015 mm. Where: . so = 8.85* 10 '12 F/m . er : 200 for ceramic material NB Give your answer in pF Answer: For the Potential Divider below, R1 is 20 Ohms, R2 is a resistor = 54.96 Ohms, and VIN = 12 V. Calculate VOUT R1 VOUT VN R2 Answer:AC mains (UK) is 220Vrms, 50Hz; calculate the current flowing through a 100W light bulb in Amps to two decimal places? Answer:What is the inductance in mH, of a 2 cm long, 54.96 turn coil, wrapped on a low carbon steel core that is 40 mm in diameter? NB The permeability of low carbon steel is 2.5 x10-4 H/m (Wb/Atm). Hint: area must be in m2. Answer: Calculate the reactance in Ohms for a 54.96pF capacitor when a frequency of 9602706.8 Hz is applied
