6 FAQs about [Teaching and answering capacitor questions]
How does a student learn how capacitors work?
A student is learning about how capacitors work. He uses the circuit shown in Figure 1 to investigate the capacitor C. Letter X labels a connection which he can make to either of the points L or M. Each cell has an e.m.f. of 1.5 V. He connects X to L. He sketches how the reading on ammeter 1 varies with time (Figure 2).
How many capacitors are connected in parallel to a power supply?
Three capacitors are connected in parallel to a power supply as shown in Fig. 1.1. A student has available three capacitors, each of capacitance 24 μF. Questions and model answers on 19.1 Capacitors & Capacitance for the CIE A Level Physics syllabus, written by the Physics experts at Save My Exams.
What is a capacitance of a capacitor?
Each capacitor has a capacitance which represents the amount of energy the capacitor can store. The greater the capacitance of a capacitor, the more energy the capacitor can store when fully charged. The most common type of capacitor is the parallel plate capacitor shown below. This diagram also shows the circuit symbol for the capacitor.
What is a capacitor and how does it work?
A capacitor is an electrical component which is capable of storing and releasing energy. The capacitor is capable of storing energy before releasing the energy to supply another component or device. Each capacitor has a capacitance which represents the amount of energy the capacitor can store.
What happens when a capacitor is connected together?
When the capacitors are connected together a current flows (1 mark) as the charge redistributes itself. When a current flows energy is lost to the surroundings due to heat dissipation from the wires (1 mark) Q3. A camera flashgun uses the discharge of a capacitor to provide the energy to produce a single flash.
How are capacitor X and Y separated?
The plates of both capacitor X and capacitor Y are separated by a vacuum. Complete Table 1.1 for this circuit. Table 1.1 How did you do? The total capacitance for two capacitors and connected in parallel is given by the equation: Using the equation given, calculate the total capacitance of the circuit shown in Fig. 1.1 in Farads, F. How did you do?
