Is this a multiple choice question? Or would you just like me to state generally the greatest influence over how big a baby elephant will grow ?
Answer:
Electrical potential is measured in units called <u>volts</u>.
Answer:
RT = 17 ohms
Explanation:
For two parallel resistances in a circuit the combined resistance is given by:
R1 = 25 ohms
R2 = 50 ohms
You replace the values of R1 and R2 in the formula for RT:
hence, the combined resitances is 17 ohms
The direction of the magnetic field around a wire depends on
the direction of the current flowing through the wire. When you
change the direction of the current in the wire, the direction of the
magnetic field around it also changes direction.
The current in every electric cord in your house changes its direction
120 times every second. So the magnetic field around every electric
cord in your house also changes its direction 120 times every second.
