A biology student wanted to investigate the behaviour of frogs with respect to shock and decided to construct an RL circuit for the investigation. The circuit is driven by a 12V DC source which is connected to a limiting resistor of 50 Q and to a switch. The other end of the switch is connected to a parallel combination of an inductor of 2H and the frog. In the experiment, the student observed that the frog moves gently when the switch is closed but moves violently for 5s when the switch is opened. Sketch the diagram of the circuit with the frog being modelled as a resistor. Explain the behaviour of the frog or why it moved gently and violently. Find the resistance of the frog. ASsume that it takes 10mA for the frog to move violently.

Please what are the steps to take in solving this question

A biology student wanted to investigate the behaviour of frogs with respect to shock
and decided to construct an RL circuit for the investigation. The circuit is driven by
a 12V DC source which is connected to a limiting resistor of 50 Q and to a switch.
The other end of the switch is connected to a parallel combination of an inductor of
2H and the frog. In the experiment, the student observed that the frog moves gently
when the switch is closed but moves violently for 5s when the switch is opened.
Sketch the diagram of the circuit with the frog being modelled as a resistor. Explain
the behaviour of the frog or why it moved gently and violently. Find the resistance
of the frog. ASsume that it takes 10mA for the frog to move violently.
