You cause a particle to move from point A, where the electric potential is 11.3 V, to point B, where the electric potential is −

BabaBlast [244]

Explanation:

The electric potential is the electric potential energy per unit of charge

$V=\frac{U}{q}$

Using this definition, we can calculate the electrostatic potential energy change between point A and B:

$\Delta U=U_A-U_B\\\Delta U=qV_A-qV_B\\\Delta U=q(V_A-V_B)$

Electron: $q=-1.6*10^{-19}C$

$\Delta U=-1.6*10^{-19}C(11.3V+25.9V)\\\Delta U=-5.952*10^{-18}J$

Proton: $q=1.6*10^{-19}C$

$\Delta U=1.6*10^{-19}C(11.3V+25.9V)\\\Delta U=5.952*10^{-18}J$

Neutral hydrogen atom: $q=0$

$\Delta U=0$

Singly ionized helium atom: $q=1.6*10^{-19}C$

$\Delta U=1.6*10^{-19}C(11.3V+25.9V)\\\Delta U=5.952*10^{-18}J$

A series circuit that is connected to a 50 V, 60 Hz source is made up of 25 ohm resistor, capacite wieh X= 18 ohms, and inductor

Allisa [31]

Answer:

the impedance of the circuit is 25.7 ohms.

Explanation:

It is given that,

Voltage, V = 50 volts

Frequency, f = 60 Hz

Resistance, R = 25 ohms

Capacitive resistance, $X_C=18\ ohms$

Inductive resistance, $X_L=24\ ohms$

We need to find the impedance of the circuit. It is given by :

$Z=\sqrt{R^2+(X_L-X_C)^2}$

$Z=\sqrt{25^2+(24-18)^2}$

Z = 25.7 ohms

So, the impedance of the circuit is 25.7 ohms. Hence, this is the required solution.
