# How do you calculate the capacitance of a coaxial cable?

## How do you calculate the capacitance of a coaxial cable?

C′=2πϵln(b/a). This is by no means solely of academic interest. The capacitance per unit length of coaxial cable (“coax”) is an important property of the cable, and this is the formula used to calculate it.

## How many watts can RG-58 handle?

RG-58 weighs around 0.025 lb/ft (37 g/m), exhibits approximately 25 pF/ft (82 pF/m) capacitance and can tolerate a maximum of 300 V potential (1800 W).

What is the difference between RG-58 and RG174?

RG58 and RG174 cables are used in vehicle boosters. The difference between the two is the better low-loss quality of the RG58 with cable length up to 20 feet compared to the RG174’s 6 feet. For large vehicles, such as RVs or boats, the RG174 is preferred.

How do you calculate the capacitance of a wire?

Adjust the frequency so that the voltage measures 0.707 of the voltage out of the signal generator (before the high impedance). You can calculate the capacitance by applying the equation for capacitive reactance Xc = 1/(2*pi*f)* C, with Xc in ohms, f in Hz, and C in farads.

### What is the impedance of RG58 cable?

50 ohm
RG 58 – Coaxial cable with characteristic impedance 50 ohm. RG 58 is used in LAN of the type CSMA/CD (Ethernet) and in systems for radio communication.

### What is the capacitance of copper?

The capacitance of the DEL of a copper electrode at the minimum has the order of magnitude (10– 20 μF/cm2) that is usual for metallic electrodes, increases to a lower extent as compared to Au and Ag when it is shifted from MCP, and is retained in the same range (several hundred μF cm2) at the bound aries of the …

What is the capacitance of a wire?

Capacitance describes the ability of two conductors, separated by an insulating material, to store charge. Capacitance in cables is usually measured in pf/m (pico farads per meter) or pf/ ft (pico farads per foot). The lower the capacitance the better the cable performance.

What is the capacitance of rg58?

RG58/U has a solid center conductor of 20 AWG bare copper. Its capacitance is 28.5 pF per foot. RG58A/U has a center conductor of 20 AWG stranded tinned copper.

#### What does a/U B/U&C/U Mean on a rg58 cable?

With reference to RG58 cable, what is the meaning for the abbreviation of A/U, B/U & C/U of a RG58 cable? RG stands for “Radio Guide” and is a military term. The 58 class has an outer diameter of 0.195 inches, 50 to 53.5 ohms impedance, and can handle up to 500 watts of HF (High Frequency) power.

#### What is rg58 coaxial cable?

RG58 is a classification of coaxial cable that is used for RF (Radio Frequency) communication systems. A coaxial cable is a multi-layered electrical cable that has an internal conductor which is enclosed by tubular insulation, which is in turn completely enclosed by a conductive cover and is

What is the size of a 58 class radio?

RG stands for “Radio Guide” and is a military term. The 58 class has an outer diameter of 0.195 inches, 50 to 53.5 ohms impedance, and can handle up to 500 watts of HF (High Frequency) power.
