FAQs on Current Flow Video Lecture - Science for Grade 5

1. What is current flow?
Ans. Current flow refers to the movement of electric charge through a conductor. It is measured in amperes (A) and is the rate at which electric charges pass through a given point in a circuit.
2. How is current flow related to voltage?
Ans. Current flow is directly proportional to voltage according to Ohm's Law. This means that as voltage increases, current flow also increases, and vice versa.
3. What factors can affect current flow in a circuit?
Ans. Factors such as the resistance of the circuit, the voltage applied, and the type of conductor used can affect current flow in a circuit. Higher resistance or lower voltage can result in decreased current flow.
4. How does current flow impact the functioning of electronic devices?
Ans. Current flow is essential for the operation of electronic devices as it allows for the transfer of electric energy. Insufficient current flow can lead to malfunctioning or complete failure of electronic devices.
5. Can current flow be controlled in a circuit?
Ans. Yes, current flow in a circuit can be controlled by adjusting the resistance, voltage, or using components such as resistors or diodes. This allows for the regulation of current flow to ensure proper functioning of the circuit.
