Toxic is the answer, toxic meaning may cause death or other health problems.
Answer:
add resistance to a circuit
Explanation:
It depends on the design in which it is incorporated. A fixed resistor has many uses, including, but not limited to ...
- dropping voltage
- limiting current
- contributing to a time delay
- adjusting frequency response
- eliminating (or creating) signal reflections
- acting as a fuse
- calibrating or trimming a response
- providing protection against electrical shock or ESD
- acting as a reference when measuring variable resistors
Given Information:
Resistance = R = 2 Ω
Capacitance = C = 4 F
Required Information:
Time constant = τ = ?
Answer:
τ = 8 seconds
Explanation:
one time constant τ is the amount of time taken when the capacitor chargers up to approximately 63 % of its maximum possible voltage.
τ = RC
τ = 2*4
τ = 8 seconds
So that means after 1 τ (8 seconds) the capacitor voltage will reach approximately 63.2 % of its maximum possible voltage.
A British thermal unit (BTU) is defined as the amount of heat required to raise the temperature of 1 pound of water by 1 degree Fahrenheit. To calculate the temperature of a water sample from the BTUs applied to it, you must know the weight of the water and its starting temperature. You can measure the weight of the water using a scale, and the temperature using a Fahrenheit thermometer. Once you have that information, calculating the temperature of the water after applying a known number of BTUs of heat is easy.
