A small disk of radius R1 is fastened coaxially to a larger disk of radius R2.The combination is free to rotate on a fixed axle, which is perpendicular to a horizontal frictionless table top, as shown in the overhead view below.The rotational inertia of the combination is I.A string is wrapped around the larger disk and attached to a block of mass m, on the table.Another string is wrapped around the smaller disk and is pulled with a force as shown.The tension in the string pulling the block is:
Parallel Circuit
An electrical circuit in which the same voltage is applied across all components, with each component directly connected to the voltage source.
Inductive Reactance
The opposition that inductance presents to alternating current, depending on the frequency of the current and the inductance value, measured in ohms.
Total Current
The complete or aggregate current flowing through a circuit, taking into account all phases and pathways.
Parallel Circuit
An electrical circuit where components are connected across common points or junctions, providing multiple paths for current.
