If your engine failed to start and you released the lever after cranking for 2 seconds, the action you should take before attempting to start the engine again is to turn off the fuel, ignition, and start switches and wait for a few seconds.
What is cranking?
Cranking is the act of turning the engine with the starter motor. This is a process that is initiated by the driver. The starter motor is switched on, which spins the flywheel of the engine. When the engine reaches a certain speed, fuel is injected, and ignition occurs, resulting in the engine running.
If the engine fails to start, it means that there was an issue with either the fuel or ignition systems. In this case, the best course of action is to turn off the fuel, ignition, and start switches and wait for a few seconds. This will allow the engine to clear any flooded fuel, which is often the cause of starting issues. After waiting for a few seconds, you can attempt to start the engine again.

a voltage amplifier with an input resistance of 40 kn, an output resistance of i 00 n, and a gain of 300 v n is connected between a 10-kn source with an open-circuit voltage of to m v and a i 00-n load. for this situation:
The current flowing through the circuit is approximately 0.4 μA.
To analyze the situation, we can use the voltage divider rule and the concept of load and source resistance to determine the voltage across the load and the current flowing through the circuit.
Given data:
Input resistance (Rin) = 40 kΩ
Output resistance (Rout) = 100 Ω
Gain (Av) = 300 V/V
Source resistance (Rsource) = 10 kΩ
Open-circuit voltage (Voc) = 20 mV
Load resistance (Rload) = 100 Ω
To calculate the voltage across the load (Vload), we can use the voltage divider rule:
Vload = Voc * (Rload / (Rsource + Rin + Rload))
Substituting the given values:
Vload = 20 mV * (100 Ω / (10 kΩ + 40 kΩ + 100 Ω))
Vload = 20 mV * (100 Ω / 50.1 kΩ)
Vload ≈ 0.04 mV
The voltage across the load is approximately 0.04 mV.
To calculate the current flowing through the circuit, we can use Ohm's Law:
I = Vload / Rload
Substituting the values:
I = 0.04 mV / 100 Ω
I = 0.4 μA
