A 60-watt light bulb has a voltage of 120 bolts applied across it and a current of 0.5 amperes flows through the bulb. What is t
Andre45 [30]

Answer:

240 ohms

Explanation:

From Ohms law we deduce that V=IR and making R the subject of the formula then R=V/I where R is resistance, I is current and V is coltage across. Substituting 120 V for V and 0.5 A for A then

R=120/0.5=240 Ohms

Alternatively, resistance is equal to voltage squared divided by watts hence \frac {120^{2}}{60}=240

A dog travels 3m East and then 4m West, what is his displacement?
RideAnS [48]

Answer:

his displacement is 5m

Explanation:

A is the stage at which a man starts walking. He's walking 4 m north, i.e. AB, then going 3 m east, i.e. BC. The displacement is the connecting straight line between the original and the final position. The displacement is thus the AC hypotenuse of the right-angle triangle. By applying the theorem of hypotenuse, we get  

⇒displacement=16+9−−−−−√=25−−√=5m

What is the resistance of a conductor
Ivenika [448]

Opposition for the current flow

Explanation:

  • Resistance is defined as the ability pf the conductor to oppose the flow of electrons through it. It is usually represented in Ohm.
  • Resistance is an important parameter in a circuit design and it should be properly designed.
  • Resistance of a conductor depends upon the material nature, length of the conductor and area of cross section.
  • In conductor, Resistance is low. It is due to that charges flow through the conductor freely.
