. The voltage across the resistor can be calculated as follows: VR=VS−Vth. =5.0−0.0495. =4.95V. If the thermistor is moved to a freezer its resistance rises to. We can calculate the voltage across the thermistor now using the same method. Find the total resistance of the voltage divider. RS=Rth+R1.To get an expression for Z in terms of R , XL, and XC, we will now examine how the voltages across the various components are related to the source voltage. which is the impedance of an RLC series AC circuit. For circuits without a resistor, take R = 0; for those without an inductor, take XL = 0; and...A current-voltage characteristic or I-V curve (current-voltage curve) is a relationship, typically represented as a chart or graph, between the electric current through a circuit, device, or material, and the corresponding voltage, or potential difference across it.The voltage drop across a resistor is nothing but the voltage value across a resistor. As we all know, a resistor is a device that offers resistance to the current flowing through it. Then, by applying Ohm's law, the resistor will offer a voltage drop across a resistive device and it is given as

How come when I connect two 9V batteries to a breadboard, each with an individual connector, the total voltage doesn't increase?

For charging

Vu(t) = iR + (1/C)(∫idt)

q = ∫idt

Vu(t) = q/C + R(dq/dt)

CVu(t) = q + RC(dq/dt)

q= ( Ke^(-t/RC) +D)(u(t))

dq/dt = ((K/(RC))(e^-t/RC)))(u(t))

at t = 0 e^0 =1, q = K + D =0 so K = - D

t=∞, q = CV = D

so q = ((CV)(1 - e^-(t/RC))

i = dq/dt = (V/R)(e^-(t/RC)) u(t)

Vr = V(e^-(t/RC) u(t)
