Calculate the current through the lamp. b Calculate the resistance of the filament of an electric fire which takes a current of 6.5 A when it is connected across a mains supply of 230 V. c Calculate the voltage which is required to drive a current of 2.4 A through a wire of resistance 3.5 12.
a). In a circuit of two lamps in series, if the current through one lamp is 5 A, what is the current through the other lamp? Answer in units of A b). If 10 V is applied to the above circuit and the voltage across the first lamp is 1 V, what is the voltage across the second lamp? Answer in units of V
A current of 1000. A flows for exactly 1 hour, through a cell in which the following reaction occurs at one of the electrodes. Mg2+ + 2e- → Mg a) Calculate the charge, in coulombs, which passes through the circuit in this time. b) Calculate the theoretical mass of Mg (magnesium metal) which is produced in this time.

When a current passes through the body, it is mainly carried by positively charged sodium ions (Na+) with charge +e and negatively charged chloride ions (Cl−) with charge −e. In a given electric field, these two kinds of ions do not move at the same speed; the chloride ions move 50% faster than the sodium ions. Part A If a current of 190 μA is passed through the leg of a patient, how many chloride ions pass a cross section...
calculate the amount of charge that passes a cross section each second and the current density of a current of 5.0 A exists in a wire of .50 cm diameters
A steady electric current flows through a wire. If 8.0 C of charge passes a particular spot in the wire in a time period of 2.0 s, what is the current in the wire? O 4.0 A O 8.0 A O 16 A O 0.25 A If the current is a constant 5.0 A, how long will it take for 14.0 C of charge to move past a particular spot in the wire? O 70 s O 14,0 s O...
