How do I really calculate these resistors?
I am learning about it.
I would like to focus on this circuit
I am trying to calculate R10 and R11.
I want Ic = 10 mA. Transistor is 2N2222A.
This is an amplifier. If I understood how amplifier …

How do I calculate the unknowns of the current equation for a RLC series circuit?
Suppose I was dealing with the following voltage equation for the RLC series circuit:
\$ v(t) = Ae^{m_1t} + Be^{m_2t} + V_s \$
To know the values of A and B I would do the two initial conditions:
…

How do I find the current equations for the RLC Series Circuit?
Let's talk about a RLC series circuit. R, L and C are in series with a battery and a switch. The switch is open. L and C are discharged.
At t=0, the switch is closed and the battery (V1) feeds the ci …

What are the initial conditions used to find the coefficients in the current equations?
Suppose a RLC series circuit. R, L and C are in series with a battery and a switch. The switch is open. L and C are discharged.
At t=0, the switch is closed and the battery (V1) feeds the circuit.
