Answer:
total current =0.06A
Explanation:
The total resistance of Resistors connected in series is given as
Rs = R1 + R2 + R3....
Here, we have that two resistors are connected in series
therefore,
Rs = 100 + 100 = 200 Ω
But current according to ohm's law is given as
I= V/R
where I= current in ampere, A
V= Voltage in volts, V and
R= Resistance, in ohms,Ω
therefore,
I= V/Rs
I = 12/ 200 = 0.06 A
C. one complete spin on its axis because the rotation is referring to the planet's period of rotation. D is called a revolution. B determines the seasons on the planets. A is called an ellipse.
Answer:
The electromotive force is the voltage measured across the cell terminals when "NO" current is being drawn. That is why electromotive forces are used in Wheatstone Bridges which measure the resistance of an external object.
Just measuring the voltage across a cell does not give one the true EMF because current drawn from the cell will cause a reduction of voltage of I * R where R is the internal resistance of the cell.
Answer:
B. Current increases because it is directly proportional to voltage
Explanation:
Ohms law is used to show the relationship between the current, voltage and resistance of a substance. The Ohms law equation is as follows:
V = IR
Where;
V = voltage (volts)
I = current (amperes)
R = resistance (ohms)
Based on these equation, it is evident that the current (I) is directly proportional to the voltage (V), hence, as the voltage increases, the current also increases. According to this question, when the voltage is tripled (increased), the current also increases because it is directly proportional to voltage.
Answer:
4940.12 m/s
Explanation:
For the net force on the moving electron to be zero, the Magnetic force must then match the electric force.
Magnetic force = Electric force
Magnetic force = qvB
Electric force = Eq
qvB = Eq
v = (E/B)
E = Electric field = 1.65 kV/m = 1650 V/m
B = Magnetic field = 0.334 T
v = (1650/0.334)
v = 4940.12 m/s
Hope this helps!!
