The following circuit was used to investigate how the current through a filament lamp varied with time, from the moment the switch was closed. (a) Explain how an increase in temperature affects the resistance of a filament lamp. (4) (b) The graph below shows the variation of pote…
(a) A 9.0V battery of negligible internal resistance is connected as shown. (i) Calculate the potential difference (p.d.) across the 120Ω resistor. (2) (ii) A student added to the circuit, as shown below, in order to determine the resistance R of a resistor. As the student adjust…
Tungsten is a metal commonly used for the filaments in light bulbs due to its high melting point. (a) The current in a filament is given by the equation $ I = nqvA $ where v is the drift velocity. Drift velocity is defined as the mean velocity of the free electrons in a current c…
