AI Generated Solution

To determine whether current will flow more easily through a thick wire or a thin wire of the same material when connected to the same source, we can analyze the relationship between resistance and cross-sectional area. ### Step-by-Step Solution: 1. **Understanding Current Flow**: Current (I) is the flow of electric charge. The amount of current that flows through a conductor depends on the resistance (R) of that conductor and the voltage (V) applied across it, according to Ohm's Law: \[ I = \frac{V}{R} ...

An electric current is passed through a circuit containing two wires of the same material connected in parallel. If the lengths and radii of the wire are in the ratio (4)/(3) and (2)/(3) , then the ratio of the currents passing through the wires will be

Assertion: Through the same current flows through the line wires and the filament of the bulb but heat produced in the filament is much higher than that in line wires. Reason: The filament of bulbs is made of a material of high resistance and high melting point.
